According to Teaching English, British Council BBC, the communicative approach is based on the idea that learning language successfully comes through having to communicate real meaning. When learners are involved in real communication, their natural strategies for language acquisition will be used, and this will allow them to learn to use the language. Example  Practising question forms by asking learners to find out personal information about their colleagues is an example of the communicative approach, as it involves meaningful communication. Based on my experience as the one who loved practicing English as part of acting, 

In my opinion who apply and encourage this method as part of teaching, everyone who really want to encourage themselves in order to be able to speak English soon need to apply it too. Here are the reasons.

• You won't be bothered by language pattern focus
• You just can't be passive, that's why you need trigger
• You make mistakes only at the beginning, soon you can correct them
• You get used to speaking English because you are doing it
• You won't think you want to be a linguist, you just want to be able to speak English fluently
